What does this mean??

Hanna • I'm 21 and have an almost 3 year old daughter. Engaged to the most amazing man. Hoping to have a baby together real soon! (:
So Im pretty new to using opk's. Yesterday I got my first positive(the first picture) and today another positive (second picture). Is it normal to have a positive 2 days in a row? So should I keep having sex until it's negative? I'm sort of confused.
